To top it off, how we get there (electronically speaking) is also Power Scaling. The goal, then, is to “ Power Scale the amp”, which will achieve “ Power Scaling the sound”. His goal is to get that same sound in the same way, at reduced volume, BUT without having to get a whole new smaller-quieter amp. Scaling Power: Player’s Perspective & Electronic Perspectiveīack to our guitar player with cranked tone. With semi-conductor technology, power control is much easier to implement, using very low-cost devices and minimal space. Electronic methods had their beginnings with had active gain elements, such as vacuum tubes. Power control methods have been around longer than electronics itself, but electronic control of power provides the greatest versatility of control attributes combined with low cost and fine resolution of control. The overdriven amp will clip its output continuously at its full rating. Attenuators can be placed between the speaker and amplifier to provide some means of control, but they tend to alter the sound and shorten tube life. For guitar amp users, controlling how loud or quiet their amp is while achieving a “cranked” sound has always been difficult.
